So, we'll be getting our hands on the Windows 8 Release Preview in the first week of June. I'm interested in what they've done to improve the Metro experience for boring old mouse and keyboard users, and if they've managed to include applications that work (as opposed to buggy preview applications).

LG is also heavily involved in Android for quite some time (and at least some of their devices are quite popular - GT540, Optimus One).
It's unlikely their problems come from WP7... (OTOH, as you can see, the two LG Androids that I remember are relatively low-end, that seems to be the problem of LG - the apparent failure to really push through large numbers of "premium", high-margin devices)
